Any pointers to how to perform the unlocking of bootloader and Magisk install ?

Recently moved from Moto X4 to Samsung A52 5G.
This will erase your phone's data so backup first
This will trip knox and prevent alot of samsung apps working

Unlocking Bootloader
1. Enable OEM unlocking in developer options
2. Turn phone off
3. Plug a usb into pc but not phone
4. Hold vol up and down and plug usb into phone
5. Wait for green screen and follow instructions to unlock bootloader (as follows)
5.5. Long press vol up on green screen then press vol up again
Installing magisk
1. Download your firmware from the internet
2. Extract the AP tar.md5 file
3. Place file on root of phone
4. Download and install Magisk (I used Canary)
5. Make sure connected to internet
6. Open Magisk and press the top install (Manager not the app install)
7. Select Install > Select and Patch a File and select the AP file you put on the phone
8. Wait for it to patch and create a new file
9. Find the new file, usually called magisk_patched in your downloads folder, but Magisk would have said what and where on the patching screen when done
10. In Odin flash this new AP file
11. If needed reinstall Magisk app, open it and let it update

To get saftey net to pass I had to use The universal saftey net magisk module found somewhere on this site. I can find it later if needed

Those are the steps I did, hope it helps

There seems to be no way to unlock the bootloader on the SM-A526U.
Everything I tried fails.
When you enable developer options on this model (SM-A526U) the unlock for the bootloader is non existent.

Correct, there is no OEM unlock option for the SM-A526U.
Reading in to it who is your service provider? Is it T-Mobile? Regardless,it seems your phone needs to either be unlocked by them or a 3rd party. Or you can try to call them and convince them you need the OEM unlock button for work purposes.

Ok so the way I updated it without wiping, although no guarantees as I am no expert with this stuff;
Note. I did disable all of my magisk modules 1st, not sure if that's a requirement, doubt it but I did it anyway
1. Manually download latest firmware
2. Extract the boot file from the AP rar
3. Convert it to a tar file
4. Patch the new boot file in Magisk
5. With Odin install all files but use Home_csc instead of just normal csc
6. wait for phone to reboot, it will say wiping for like half a second and then boot loop to a wipe data screen, don't wipe data!
7. Hard turn the phone off and re enter download mode
8. With odin patch the magisk boot file you made earlier.
9. It should now boot and upgrade
